How to Warm Up a New Sending Domain

A new domain has little or no sending history. Start with fully configured authentication, real inboxes, and contacts who are likely to engage. Send a small number of useful messages and increase volume only when delivery and reply signals remain healthy.

Avoid sudden spikes, old lists, repeated templates, and unattended replies. Monitor bounces, complaints, and blocks. Warmup is not a shortcut around consent or list quality; it is a controlled way to establish legitimate sending behavior.
